Product Introduction

A PTFE lined diaphragm pump is a positive displacement pump that uses a combination of the reciprocating action of a PTFE diaphragm and suitable valves on either side of the diaphragm to pump a fluid.

All contact parts inside of pump body is PTFE lined and there is no leakage point and no corrosion to the pump body. J.H. Euipment can provide you two kinds of PTFE lined diaphragm pumps, one is air-operated and the other is motor-driven.

Working Principle

When the volume of a chamber of pump is increased (the diaphragm moving up), the pressure decreases, and fluid is drawn into the chamber. When the chamber pressure later increases from decreased volume (the diaphragm moving down), the fluid previously drawn in is forced out.
Finally, the diaphragm moving up once again draws fluid into the chamber, completing the cycle.
